    • The invention includes methods of processing an initial di-carbonyl compound by conversion to a cyclic compound. The cyclic compound is reacted with an alkyating agent to form a derivative having an alkylated ring nitrogen. The invention encompasses a method of producing an N-alkyl product. Amonia content of a solution is adjusted to produce a ratio of ammonia to di-carboxylate compound of from about 1:1 to about 1.5:1. An alkylating agent is added and the initial compound is alkylated and cyclized. The invention includes methods of making N-methyl pyrrolidinone (NMP). Aqueous ammonia and succinate is introduced into a vessel and ammonia is adjusted to provide a ratio of ammonia to succinate of less than 2:1. A methylating agent is reacted with succinate at a temperature of from greater than 100 °C to about 400 °C to produce N-methyl succinimide which is purified and hydrogenated to form NMP.
    • 本发明包括通过转化成环状化合物来处理初始二羰基化合物的方法。 该环状化合物与烷基化剂反应形成具有烷基化环氮的衍生物。 本发明包括生产N-烷基产物的方法。 调节溶液的氨含量以产生约1:1至约1.5:1的氨与二羧酸盐化合物的比率。 加入烷基化试剂并将初始化合物烷基化并环化。 本发明包括制备N-甲基吡咯烷酮(NMP)的方法。 将氨水和琥珀酸盐引入容器中并调节氨以提供小于2:1的氨与琥珀酸盐的比例。 使甲基化剂与琥珀酸酯在大于100℃至约400℃的温度下反应以产生N-甲基琥珀酰亚胺,将其纯化并氢化以形成NMP。

    • The invention includes methods of producing dianhydrosugars. A polyol is reacted in the presence of a first catalyst to form a monocyclic sugar. The monocyclic sugar is transferred to a second reactor where it is converted to a dianhydrosugar alcohol in the presence of a second catalyst. The invention includes a process of forming isosorbide. An initial reaction is conducted at a first temperature in the presence of a solid acid catalyst. The initial reaction involves reacting sorbitol to produce 1,4-sorbitan, 3,6-sorbitan, 2,5-mannitan and 2,5-iditan. Utilizing a second temperature, the 1,4-sorbitan and 3,6-sorbitan are converted to isosorbide. The invention includes a method of purifying isosorbide from a mixture containing isosorbide and at least one additional component. A first distillation removes a first portion of the isosorbide from the mixture. A second distillation is then conducted at a higher temperature to remove a second portion of isosorbide from the mixture.
    • 本发明包括生产二脱水糖的方法。 多元醇在第一催化剂存在下反应形成单环糖。 将单环糖转移到第二反应器中,在第二反应器中在第二催化剂的存在下将其转化成二水糖醇。 本发明包括形成异山梨醇的方法。 初始反应在固体酸催化剂存在下的第一温度下进行。 最初的反应包括使山梨糖醇反应生成1,4-脱水山梨糖醇,3,6-脱水山梨糖醇,2,5-甘露糖醇和2,5-戊二酸。 利用第二温度,1,4-脱水山梨糖醇和3,6-脱水山梨糖醇转化为异山梨醇。 本发明包括从含有异山梨醇和至少一种附加组分的混合物中纯化异山梨醇的方法。 第一次蒸馏从混合物中除去第一部分异山梨醇。 然后在较高温度下进行第二次蒸馏以从混合物中除去第二部分异山梨醇。
